BR NBL prototype 10800 Profile and Models

Designed as a replacement for medium sized steam locomotives, this prototype diesel electric was ordered by the London, Midland and Scottish Railway in 1946, but did not enter service until two years after the nationalisation of British Railways in 1948. The locomotive was the first mixed-traffic diesel locomotive in the UK, and was operated on a variety of passenger and freight services in the Midlands and South of England throughout the 1950s. After withdrawal, the locomotive was used for testing early AC transmission technology and was based at Brush Traction's Loughborough Works, being renamed "Hawk". The tests were successful, however the locomotive quickly became obsolete and was scrapped by 1976.
